The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a directional coupler. The loop mirror is implemented using a Sagnac configuration to have the ...

The prospect of using humanoid robots in practical applications attracts an important research effort and the latest steps forward in robot technology show many remarkable achievements where design aspects, control systems ...

Data warehouses (DW) integrate different data sources in order to give a multidimensional view of them to the decision-maker. To this aim, the ETL (Extraction, Transformation and Load) processes are responsible for extracting ...

This paper presents the findings of an empirical study of a prototype for children with speech disorders. --- the purpose of this work was to evaluate the interaction process of children on the Dice of Phoneme DoF (DoF) ...

This paper proposes a new method to estimate the 3D motion of a vehicle based on car-like structured motion model using an omnidirectional camera and a laser rangefinder. In recent years, motion estimation using vision ...

Society evolves at a rapid pace, integrates the latest everydays life technologies and squeezes the benefits of innovation. At the same time, universities follow these same steps, creating great possibilities by providing ...

Intelligent environments need interactions capable of detecting users and providing them with goodquality contextual information. In this sense we adapt technologies identifying and locating people adjusting their requirements. ...

A novel ring resonator configuration with Bragg gratings is presented. The stability of this configuration is studied by a z-transform technique. A router design with a FWHM of 17 MHz, a -40-dB rejection ratio, and a 15-dB ...

A polarization independent reconfigurable optical demultiplexer with low crosstalk between adjacent channels and high number of potential allocated channels is designed on silicon on insulator technology. On to off state ...

Feet-ground interactions influence the legged robot's stability. In this paper, a high-resolution indirect force measurement for hydraulic-legged robots is presented. The use of pressure transducers placed at one or both ...
